Module 1 | Properties and structure of matter
Content 4: Bonding
Lesson 1 | What binds atoms together in elements and compounds?
-
investigate the role of electronegativity in determining the ionic or covalent nature of bonds between atoms
Lesson 2 | Differences between ionic and covalent compounds
-
investigate the differences between ionic and covalent compounds through:
– using nomenclature, valency and chemical formulae (including Lewis dot diagrams) (ACSCH029)
– examining the spectrum of bonds between atoms with varying degrees of polarity with respect to their constituent elements’ positions on the periodic table
– modelling the shapes of molecular substances (ACSCH056, ACSCH057)
Lesson 3 | Spectrum of bonds and shapes of molecules
-
investigate the differences between ionic and covalent compounds through:
– using nomenclature, valency and chemical formulae (including Lewis dot diagrams) (ACSCH029)
– examining the spectrum of bonds between atoms with varying degrees of polarity with respect to their constituent elements’ positions on the periodic table
– modelling the shapes of molecular substances
Lesson 4 | Allotropy
-
investigate elements that possess the physical property of allotropy
Lesson 5 | Types of bonding in substances
-
investigate the different chemical structures of atoms and elements, including but not limited to:
– ionic networks
– covalent lattices (including diamond and silicon dioxide)
– covalent networks
– metallic structure
Lesson 6 | Intermolecular and intramolecular bonds
-
explore the similarities and differences between the nature of intermolecular and intramolecular bonds and the strength of the forces associated with each, in order to explain the:
– physical properties of elements
– physical properties of compounds (ACSCH020, ACSCH055, ACSCH058)
